Carel ACC Series

ACC is a microprocessor controller that is used to prevent the formation of condensate on cold surfaces, such as display case windows, measuring the dewpoint and consequently heating the cold surface so as to maintain the temperature above the dewpoint. Heating is performed by controlling the voltage applied to door heaters, using phase control integrated into the device.


  • Dewpoint calculation
  • Manual offset setting
  • Programmable digital input (alarm or enabling signal)
  • Master/Slave function
  • Serial interface for connection to supervisory systems or local network
